A flaw was found in the OpenShift Container Platform build system. A user with the edit ClusterRole can inject arbitrary environment variables, such as LD_PRELOAD or http_proxy, into docker-build containers through the buildconfigs/instantiate API. This incomplete fix for a previous vulnerability allows for information disclosure, specifically impacting the confidentiality of build traffic.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
